Re: [PATCH] usb: typec: ucsi: acpi: don't dereference a missing ACPI companion

Hi Greg,

Fair enough - my Reviewed-by was about the fix being technically
correct, not about whether we want it, and it takes a driver_override
write plus the bind to get there, which is a fairly deliberate root
action.

The one question I'd leave open is the syzbot noise - this report came
in recently, so if the fuzzer is still exercising the override+bind
path there will likely be more of these. If those reports can be
identified and closed as noise, the patch is indeed solving a
non-problem.

Yogesh, either way the analysis in your patch was solid - the bind
path research was right on.

Thanks,
Huang Wei
